I will lose all the data.
Why haven't you still used 4TB E: drive, you created previously?
1. Move data from D: to E: or copy using robocopy preserving timestamps;​
2. Delete 4TB pool;​
3. Recreate pool as 12TB or set up 12TB mirrored volumes using dynamic disks (instructions in post #12);​
4. Move data back or copy using robocopy preserving timestamps.​

4 physical drives.
2x 4TB, that are actually empty. One is connected as E:
2x 12TB that are a mirrored pool, but are seen as only 4TB. (D: )
The data is currently living on the 2x 12TB pool. (D: )

So copy the data to the E as mentioned above.

Fix the 12TB pool. (or do away with the Pool concept completely).
Then, copy the data to one of the 12TB.

Yes,
But if "Move" fail is a problem
If move fail creates a disaster of files spread across both.
actually moving was creating this issue I'm trying to fix using robocopy.



So what I'm thinking is to fest make a copy to one 4TB HDD
and then a robocopy move to the other 4TB HDD

Personally, I would skip Step 3.
Individual 12TB drives.
Yes me too because in my experience is the first time using Storage Spaces and fails at some point.
Is buggy, a mess if you read the pdf and is not simple to go out from it.
I wish to use it but I'm not going to give it a second chance.
I need more valid reliability, not more problems.

Well DS before mention:
"simple task into a giant, messy nightmare? Robocopy is a very niche thing, for people with large datasets with particular parameters and unnecessary for people without those needs."
What a normal Windows user need is a Windows button that allows copy ("move" way) one drive to another. I mean the content, not the vulture.
Without losing date stamp and user time. A "move" that does not delete the origin.

Robocopy is to complex for the average user. I'm still reading the best option and it does not include a Windows UI.

They care but they can live with it. They do not know how to report it as a bug (and do not have the time).
And Windows developers do not care too much about fixing very old problems (example link),
They just make new features but new features with bugs are not features at all.
Yes, create a "cloud" community around that bug...
Windows thinks is an API when in reality is the data container of the memorys of all humanity.
We care about them.
